Inventor: ERICSSON HANS BIRGER
IPC: H02H7/097
Filed: 1997-05-09
Granted: 2005-02-01
Abstract: A method and a device for electrical braking of an all-mains motor by which disconnection of supplied feed current to the motor causes an electric switching operation, whereby electric current arranged to cause a reversed rotary direction for the rotor (1) of the motor is supplied. According to the invention, supplied braking power (P) is controlled and reduced on basis of the successive reduction of rotary speed for the motor until the rotor (1) of the motor has substantially completely ceased to rotate, preferably substantially corresponding to an inverted "soft start" for the motor, whereafter supplied braking current feed is interrupted. It is advantageously monitored whether or not normal start of the motor has been performed, electric switching to braking only being made possible provided that such a start sequence has been indicated.

Abstract: In a Data Access Transport Service (DATS), Data Service Providers (DSPs) sha re dial-in access (e.g. analog modem or Integrated Services Digital Network (ISDN) access) resources from a common pool maintained by a Local Exchange Carrier (LEC) (or potentially a DSP). A system is disclosed wherein a Network Controller (NC) performs the  role of DSP service partitioning, quota enforcement, and resource load balancing to ensure that a DATS provider can provide a high quality of service (availability, response time & consistent bandwidth) to subscribed DSPs and their end-users. The Network Controller assits in Internet Data call establishment and tear-down, with the ability to refuse calls when the associated DSP has exceeded its service  quota. The Network Controller also assists in the routing of calls to one of the DSP's Network Gateways (or data routers), using a load balancing scheme that maintains a pre-defined relative load on given DSP Network Gateways. The Network Controller will also provide an implementation that supports Multilink Point to-Point Protocol (MLP) and 56 kbps data calls for ISDN BRI access. Additionally, the Network Controller will perform such functions as statistics collection, and network element administrative control. The Network Controller can be positioned to provide similarservice control functionality with higher speed access technologies such as Asymmetric Digital Subscriber Loop (ADSL) and high-speed cable modems.

Granted: 2006-05-16
Abstract: A process for upgrading heavy crude oil production is described which involv es adding a diluent, or solvent, which is a light hydrocarbon to reduce the viscosity and specific gravity of the crude oil being processed. After dilution, the emulsions in the crude are broken and the separation of the crude into the components follows, aided by a second injection of diluent. This upgrades the crude and enhances the amount recovered for processing at a refinery. A high asphalt content of a heavy crude can also be tolerated in the practice of this invention resulting in environmentally-benign solids and water exiti ng a process which due to the modularization of equipment can be practiced at the well-head itself.

Title: Anti-rattle trailer hitch
Inventor: YOUNG DAVID A
IPC: B60D1/14
Filed: 2000-05-08
Granted: 2005-04-05
Abstract: A hitch assembly generally includes a hitch receiver that retains an insert by a pin.    The pin is preferably hook-shaped and includes a primary pin segment and an engagement terminus. The primary pin segment defines a primary axis transverse to the common longitudinal axis of the hitch assembly. When assembled, the primary segment passes through an aperture located in a first wall of the hitch receiver, the insert aperture of the insert and another aperture in the second wall of the hitch receiver.  As a fastener is threadably engaged with a threaded portion of the pin, the fastener pulls the primary pin segment through the hitch receiver and drives the engagement terminus through the second aperture against the insert. The fastener thereby introduces tension in the pin to restrict movement of the insert relative to the hitch receiver and minimize free-play therebetween. In one embodiment, a tamper resistant secondary retainer provides a lock which engages a conical end of the pin.
